How does the concentration of acid affects the speed of reaction of indigestion tablets?
as fast as it happens
What is the majority of nutrient absorption that takes place?
The majority of nutrient absorption occurs in the small intestine, specifically in the duodenum, jejunum, and ileum sections. Here, digested food is broken down into its constituent nutrients—such as carbohydrates, proteins, and fats—which are then absorbed into the bloodstream. The villi and microvilli lining the small intestine increase the surface area to optimize this absorption process, ensuring efficient nutrient uptake.
A function of the circulatory system in a mammal?
Mammals have a closed Circulatory system. Parts of the system include a heart and veins. It is complex.
What breaks down cellular food and waste?
Cellular food is broken down by the process of cellular respiration, which converts glucose into energy (ATP) within the mitochondria. Waste products from cellular metabolism are broken down or eliminated from the cell through processes such as exocytosis, lysosomal degradation, or excretion.
Lacteals are lymphatic vessels found in small intestinal villi. While other nutrients such as amino acids and saccharides are absorbed into the blood stream, lacteals and the lymphatic system are used to absorb fats.
Peristalsis, a series of muscle contractions in the intestines and stomach that help to push the food through your digestive tract.
What do chewing and the action of bile have in common in the digestive system?
They both break down a certain thing. Bile breaks down fats while chewing breaks down carbohydrates in simple sugar
Our bodies do not need bacteria to digest meat. During digestion, the stomach contains a powerful mixture of an enzyme named pepsin and hydrochloric acid. These two compounds compliment each other's strength to produce a powerful brine that breaks certain peptide bonds (bonds between individual amino acids in proteins), reducing the digested protein to tiny bits. The partially-digested proteins then move on to the duodenum of the intestine, where a vast array of specialized protein-breaking enzymes finish the job the pepsin started. Hope this helped.
Which digestive organs produces pepsin?
Pepsin is an enzyme in the stomach that begins the digestion of proteins by splitting them into smaller pieces. It is a gastric protease; pepsin is secreted in an inactive form, pepsinogen, which is activated by stomach acid. enzyme produced in the mucosal lining of the stomach that acts to degrade protein.
Hydrolysis and other chemical reactions are used during the process of digestion to break large molecules down into their smaller components. Hydrolytic reactions are exergonic reactions.
